From 1985 to 1992, CHNSEAL Group experienced seven years of international seal trade and accumulation of technical parameters. In 1992, CHNSEAL Group established its first blockade manufacturer "Wenzhou CHNSEAL Group Co.,Ltd. (the predecessor of CHNSEAL Group Group).

In 1995, CHNSEAL Group participated in the analysis of the quality and relevant standards of the international blockade industry and put forward a development model with "three continuous" as the enterprise concept. After 16 years of unremitting efforts, CHNSEAL Group has truly grasped the practical technical parameters of design, production and testing required by the international isodis / 17712 quality standard, and surpassed the international standards in many fields. Therefore, CHNSEAL Group has become the most powerful manufacturer in the domestic container seal and tie industry and the designated production unit of many shipping companies, oil fields, banks, express companies, power companies and water plants at home and abroad. At the same time, CHNSEAL Group also provides technical and production cooperation for many foreign well-known seal enterprises.

Mechanical safety seal refers to the safe sealing state and safety factor of goods in the process of transportation and storage. It has the characteristics of tensile resistance, bending resistance, impact resistance and distortion resistance. As long as the seal is in the locked state, the goods are safe, which greatly reduces the human, material and financial resources consumed by goods in the process of transportation and storage and shortens the cycle of intermediate links, Thus, the efficiency is improved. Once the blockade is destroyed, it can not be reused for the second time. Products can be divided into bayonet seals and tension seals according to their structure.

Snap type seals are divided into snap type high security seals, snap type high security seals and snap type padlock security seals. The products are widely used in logistics, shipping companies, foreign trade commodity inspection, factory inspection seals and one-time anti-counterfeiting and anti-theft sealing of container doors of various transportation vehicles.

Tensioned seals are divided into tensioned steel wire seals, tensioned plastic seals, tensioned iron sheet seals and instrument seals. All with tensioned structural devices belong to this category.
